Genes affected

FGF23 (HGNC:3680): (fibroblast growth factor 23) This gene encodes a member of the fibroblast growth factor family of proteins, which possess broad mitogenic and cell survival activities and are involved in a variety of biological processes. The product of this gene regulates phosphate homeostasis and transport in the kidney. The full-length, functional protein may be deactivated via cleavage into N-terminal and C-terminal chains. Mutation of this cleavage site causes autosomal dominant hypophosphatemic rickets (ADHR). Mutations in this gene are also associated with hyperphosphatemic familial tumoral calcinosis (HFTC).

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -19 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 10 curated pathogenic missense variants (we use a threshold of 10). The gene has 2 curated benign missense variants. Gene score misZ: 0.39751 (below the threshold of 3.09). Trascript score misZ: 0.82334 (below the threshold of 3.09). GenCC associations: The gene is linked to autosomal dominant hypophosphatemic rickets, tumoral calcinosis, hyperphosphatemic, familial, 2, tumoral calcinosis, hyperphosphatemic, familial, 1.

BP4

Computational evidence support a benign effect (MetaRNN=0.010053068).

BP6

Variant 12-4370516-G-A is Benign according to our data. Variant chr12-4370516-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 585858.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00296 (449/151894) while in subpopulation AFR AF = 0.0103 (428/41412). AF 95% confidence interval is 0.00953. There are 3 homozygotes in GnomAd4. There are 224 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 3 AD,AR gene
